IMPROVEMENT lN SUPPLEMENTARY GRATlNG FOR STOVES, FURNACES, dc

Specification forming part of Letters Patent No. 14,356, dated March 4,1856.

To all whom it may concern.-

Be it known that I, B. F. FOERING, of Philadelphia, in the county ofPhiladelphia and State of Pennsylvania, have invented a new and improvedmode of removing slate, cinders, clinkers, and other impureorincombustible materials which accumulate at the bottoms of thefire-chambers of stoves, grates, furnaces, &c., in which anthracite coalis consumed; and I do hereby declare that the following is a full,clear, and exact description of the same, reference being had to theannexed drawings, making apart of this specification, in which- Figure 1is a front view of the grate of a stove or furnace. Fig. 2 is atransverse vertical section of the same. Fig. 3 is a horizontal sectionof the same, a 00, Fig. 2, showing the plane of section.

Similar letters of reference indicate corre sponding parts in theseveral figures.

The nature of my invention consists in inserting a sup idementarygrating within the fire-chamber a requisite distance above the usualgrating or fire-grate, so that the latter may be removed or let down,the coal being held or sustained by the supplementary grating,while theslate, cinders, &c., are removed from the lower part of thefire-chamber.

In the annexed drawings, A represents the fire-chamber of a stove orfurnace.

B is the grate, and G is thefire-bars or grate at the bottom of thefire-chamber. The grate O is hinged or jointed at its back end, so thatit may be let down when required.

D is a supplementary grating, which is formed of a series of rods, a,the outer ends of which are pointed, and the inner ends are secured to abar, I), to which handles 0 c are attached. (See Figs. 2 and 3.)

The stove or furnace is cleaned out as follows: The supplementarygrating D is inserted in the fire-chamber A through the grate B, theinner ends of the rods a resting upon a crossbar, (I, of the grate,which bar is at a suitable height from the grate O, the outer ends ofthe rods resting, if necessary, upon a ledge, e, at the back part of thefire-chamber. lhe bottom or fire grate, O,is then let down while thecoal is burning in the stove, and the slate,

cinders, clinkers, and all impure incombustible substances which settleor fall to the bottom of the fire-ehamber, and which are below thesupplementary grating, are removed, the coal being supported or held bythe supplementary grating D. When the fire-chamber drical stoves, sothat the grating may conform to the shape of stove. It would bepreferable to have the rods a connected to a bar, I), as shown; butdetached rods maybe employed.

The advantages of this improvement is that the stove or furnace may becleaned or have all impure or foreign substances which obstruet thedraft removed from itwhile the coal is burning, so that a continuousfire may be kept up. here anthracite coal is used clinkers will form,especially during a rapid combustion, and the clinkers, slate, and otherimpurities gradually settle to the lower part of the fire-chamber. Ifthese are not removed the draft will be checked and the fire correspondently reduced. Consequently it has been hitherto necessary to allowanthracite coal-fires to burn out frequently in order to clean out thefurnace or stove.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

Cleaning or removing foreign substances such as slate, einders,clinkers, &c.from stoves, furnaces, or other heating devices in whichanthracite coal is burned by means of the supplementary grating Dapplied to the stove or furnace or inserted within it, substantially asherein shown and described.
